Iscar 5920009 Laydown Threading Insert 16ERM AG60 IC-250

Product Description

The ISCAR 5920009 is a laydown threading insert designed for external thread-cutting operations on CNC lathes and turning centers. This solid carbide insert carries the IC-250 grade with a PVD-applied TiN coating, targeting hard, abrasion-resistant performance on steel, stainless steel, and cast iron workpieces. It is configured as a right-hand, partial-profile 60-degree thread form insert, covering a thread pitch range of 48 to 8 TPI (0.50 to 3.00 mm pitch). The inscribed circle measures 3/8 inches (0.3750 inches) and thickness is 0.1430 inches. It belongs to ISCARs ISCARTHREAD series and is suited for machinists and tooling specialists working in precision threading applications.

This insert is intended for external threading operations in production and job-shop environments where consistent thread quality across steel, stainless steel, and cast iron is required. The AG60 designation indicates a 60-degree partial profile geometry, making it adaptable across a range of unified and metric thread standards without requiring a dedicated full-profile insert for every pitch. The M chipbreaker geometry is suited for moderate cutting conditions. Insert size code 16ER confirms fitment in standard 16-series laydown threading toolholders commonly found on manual and CNC turning equipment.

Key Features

• 60-degree partial profile form covers 48 to 8 TPI and 0.50 to 3.00 mm pitch range
• Right-hand external thread orientation, 16ER insert style
• M chipbreaker for controlled chip flow in moderate threading conditions
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use in 16-series laydown external threading toolholders accepting ER-style inserts. Compatible with workpiece materials classified as steel (P), stainless steel (M), and cast iron (K) per ISO material grade designations.

Installation Notes

Threading inserts of this type are installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or clamp-screw driver to the toolholder manufacturers specified seating procedure — do not overtighten the clamping screw. Verify insert seating and orientation before resuming cutting operations, and confirm thread pitch selection against the part drawing before the first pass.
